I have developed a restapi using SpringBoot. I would now like implements object manipulation by jsonpatch.
In general, I would like the restrict the patch to certain properties. For example, in addition to my Person Dto, I also have a PersonPatch Dto that only contains the editable fields. Currently I do this:
- Receive JsonPatch
- Pull person entity from database
- Generate PersonPatch Dto by Mapstruct
- Apply jsonpatch to DTO and validate it
- map PersonPatch-Dto to person-entity and save entity to database
I'm assuming this proceed is okay?
However, now I have the following problem: My Person DTO has a field called "numbers". This field now contains a list of objects of type telephone number (type, telephone number, notice).
If I now want to add a new number, it's relatively simple:
[ {
"op": "add",
"path": "/numbers/-",
"value": {
"type": "private",
"number": "0018181",
"notice": "my notice"
}
}]
However, I have problems deleting a phone number. Here I can't say by jsonpatch "delete phone number "0018181". I must enter the id of the list element. In individual cases, this also works because I can count the list elements in the frontend. However, I get a problem if another person has made changes to the person in the meantime. My frontend then assumes that I want to delete id 3, but on the server side it is already a different id due to changes.
How can I make sure that I am really deleting the correct data when deleting?
